John 16:8

5 and now I go away to Him who sent me, and none of you doth ask me, Whither dost thou go?

6 but because these things I have said to you, the sorrow hath filled your heart.

7 `But I tell you the truth; it is better for you that I go away, for if I may not go away, the Comforter will not come unto you, and if I go on, I will send Him unto you;

8 and having come, He will convict the world concerning sin, and concerning righteousness, and concerning judgment;

9 concerning sin indeed, because they do not believe in me;

10 and concerning righteousness, because unto my Father I go away, and no more do ye behold me;

11 and concerning judgment, because the ruler of this world hath been judged.
